Thank you everyone who has responded so quickly. I really didn't expect this much of a response...

SvanThor, Rohaq, QueenCopper... I really do appreciate all of you taking the time to reply to me. Rohaq, the last time I had feelings of despair this deep and intense was when I was dumped by my first boyfriend a little over 5 months ago, which sent me into a deep depression that I eventually came out of. I don't have a clear reason for this time though, but the feelings are intense. I know I'm missing a friend who is not responding to my messages on Facebook. I think I could eat something if I could actually get up, but there is not much incentive to because I don't feel painfully hungry and I'm trying to lose weight anyway. But I know I haven't eaten enough.
